T0011 FOR MANPULATING SLIT RIB/IS.

Specification of LettersPaten-t. Patented l'vll", 23, lllgllll Application filed November 5, 1917. Serial No. 200,397.

To all fr0/wm t may concern:

Be it known that I, CLARENCE A., Born, a citizen of the United States, and resident of Milwaukee, in the county of Milwaukee and State of W'isconsin, have invented certain new and useful improvements in rlilools for llianipulating Split Rims; andy I do hereby declare that tie following is a full, clear, and exact description thereof.

My invention relates to new and usefull improvements in tools for expandingand contracting split rims, whereby to faciliyl tato theirmanipulation with respect to tires associated therewith.

lt is in general the object of-my invention to simplify the structure and improve the cfiiciency of tools of this character.

It is more specifically my object to pronvide a tool` of this nature which may be most readily manipulated, particular] with respect to its attachment to and detac ment y from the rim.

lVith the above and other objects and advantages in view, the invention resides more particularly in the novel combination, f0rmation and arrangement of parts hereinafter described and pointed out in the appended claims.

In the drawings: p

Figure l is anelevational View of the end -portions of a split rim in expanded position, and showing my improved. tool associated therewith in its initial position for contracting the rim to procure its detachment from the tire.

Fig. 2 is a side elevational View of the rim ends in partially contracted position, and showing my tool attached thereto for completing the contracting operation.

Fig. 3 is a transverse sectional view throughV a portion of the rim, shgwing one of the attaching members of my tool' engaged therewith.

Referring now more particularly to the accompanying drawings, my improved tool comprises a preferablv straight lever bar 5 to one end of which is pivoted theinner end of a rim gripping member comprising a bar f6 bent to provide angularly disposed portions, the free end of the outermost of which is extended laterally and then in-. wardly to form 'a hook portion 7 adapted to engage about one side wall `portion 8 of a split rim 9, with itsy bill extending between the side wall portion 8 and a tire disposed on the, rim. Pivoted to the lever 5 inwardly ofthe rim gripping bar 6 is a link l0 and this link has its free end beveled to provide, a fnlcrum point ll and has pivoted thereto immediately inwardly of this fulcrunr point` 6o than the distance between its pivotal connection 10a and the bend of the :gripping bar 6 when the said bar is entendedfwith re- '7o spect to the lever. i

Taking up now the operation of the tool, which is divided into two phases, the tool is first applied, as shown in Fig. l, with the hook 7 of the gripping bar 6 disposed about 'lo the wall of one end portion of the rim, and the fulorum point 11 of the link abuttingly engaged against the other end portion 'of the rim. A rocking movement of the lever will thus serve to procure relative lateral so movement of the end portions of the rim whereby they assume the position shown in i Fig. 2. The tool is then detached from the rim and again applied, with the ,f grippingf zbars 6 and l2 .spread and bothhaving their hooks engaged about wall portions of the ends of the rim. Rocking of the lever in a counter-cloelrwise direction, as, indicated in Fig. 2, will then procure. an ecient contracting movement of the' rim to permit it to be readily withdrawn from the tire. llt is noted that the gripping bars 6 may have a slight rocking action "with respect to the rim ends, whereby to caert a frictional lock thereon.

Thus my im roved tool may be most readily and qnicA ly manipulated, in contradistinction to those types of rim removing tools necessarily embodying rim gripping members which must be fastened to both sides of the rim by suitable adjusting means. In expanding the lrim within a tire, the' tool is applied to the rim inthe general manner shown in Fig. 2, and the lever 5 rotated in a clockwise direction. i

What is claimed is:

l. A tool for manipulatin split rims comprising4 a lever, rim ipping means at one end thereof, a link pivoted to the lever adjacent said end thereof, tire gripping means at the free end of the link, and said link. being adapted to abnttinglv engage one end of a split rim upon engagement of the riin gripping means of the lever with the other end of the split rim, whereby to `Serve as a ulcrum for said lever to procure gtransverse movement of the split rim ends.

2. Atoolfor manipulating split rims comprising a lever, a link pivoted thereto adjacent one end and beveled to form a fulerum point at its free end, tire gripping 10 hars pivoted to the free enol of the link and the specified end of the lever and each bar ineludinga laterallv directed outer portion terminating in a hook portion having its bill adapted to engage the inner face of the side wall of the rim. x

In testimoinT that I claim the -ioregomg I have hereunto set my hand at Milwaukee. in the county of Milwaukee and State of Misconsin, in the presence of two witnesses.
